blank page returned from validate

I'll preface this by saying that i am extremely new at using struts. Finally got around the various error and display issues and now i'm just not getting anything. when i submit the form i get a blank page (/testing.do), i was under the impression that it would return to the page indicated in the input parameter of the action-mapping. The following is the code that i'm using, any input would be appreciated.

ok... figured it out... if you are going to override validate make sure you aren't being a moron and overriding the wrong one... override the one that takes javax.servlet.http.HttpServlet as an argument. Secondly, something that really irritated me initially, your form elements must start with a lower case character and if you are using a ActionForm it will automatically try to compare parameters (introspection) by prefacing your form elements with get/set and changing your first character to uppercase... as a result make certain that you aren't thinking of that in your validate and just focus on the form element names (i didn't change them when i changed the forms)....
